I am trying to charge this Li-Ion battery (https://www.sparkfun.com/products/339) with a small dc generator.
It is attached to an anemometer and i can get 100 mV and 20 mA in a normal windy day.
I have this dc/dc converter to boost the 100mV to 4.1V so i can charge the battery (http://www.linear.com/product/LTC3108)
What i need now is to manage the battery so it won't overcharge and don't let it discharge completely.
This circuit is to power an Arduino Fio, so i need low power.
Can someone help me?
